Detailed Description

The WAI 11527N alternator is built to replace worn or failing charging units in vehicles that rely on consistent electrical output for ignition, lighting, accessories, and onboard systems. Its 130 amp output supports the charging demands found in late-model Ford Crown Victoria, Ford E-150, Ford E-250, Ford E-350 Super Duty, Lincoln Town Car, and Mercury Grand Marquis applications. The internal regulator and internal fan help simplify the design while maintaining the charging characteristics expected from a DENSO-style unit.

This part cross-references Remy 11527 for the same application. It also references OE-style numbers 104210-1270, AW7T-10300-AA, and AW7Z-10346-A.
